QB#54 - Add support for banning

As we get players, we will get trouble makers, that much is already clear. We need the ability to ban users for a configurable amount of time, as well as preset amounts. These SHOULDN’T effect the forum bans however a ban on the forum SHOULD be a ban in game also (I think).

Something like this might do:

#ban PLAYERNAME [[[Y:]D:]H:]M REASON

eg.

#ban testuser 1:4:6:3 Because you're a tool

This would ban ‘testuser’ for 1 year, 4 days, 6 hours and 3 minutes because he’s a tool. He would be informed of such when trying to login.
